I'm not sure if it's reviewing toys or simply owning more toys that's done it.
When you don't have a vibrator at all, then you get what you can afford, but after you already have one, then you can take your time to save up for a really good one. And also playing with the $20 vibe will give you an idea of what sort of features you want in your first $120 vibe. That's pretty much what I've done with all different types of toys - get an affordable one first, then upgrade.
My goal is to eventually have one Best of Category toy for all the various types. I have a Best Clit Vibe (Lelo Mia), a Best G-Spot Vibe (G-Ki), Best G-Spot Dildo (Pure Wand), Best Orgasm Gel (Durex Utopia) and so on. I still don't have a Wand Vibrator, which I can't get from Eden because I live in the UK (voltage differences), and I haven't yet found a Best Butt Plug.
Once I get a Best of all the various categories, I'm not sure what I'll do after that. Retire from sex toy reviewing?
Okay, not really. By then, there will likely be better options in all my categories (except the Pure Wand - I can't really believe that will ever be beaten.)
